A new method has been developed for the synthesis of imidazo[1,2‐a]pyridines, imidazo[2,1‐b]thiazoles, and benzo[d]imidazo[2,1‐b]thiazoles attached to a cycloalkyl or saturated heterocycle containing a tertiary hydroxy substitution. Readily available substituted 2‐aminopyridines, 2‐aminothiazoles, and 2‐aminobenzothiazoles were treated with bromohydroxycycloalkyl ethanones to afford the desired products
已开发出一种新方法,用于合成与环烷基或饱和烷基相连的咪唑并[1,2- a ]吡啶,咪唑并[2,1– b ]噻唑和苯并[ d ]咪唑并[2,1– b ]噻唑含叔羟基取代的杂环。用溴羟基环烷基乙酮处理易得的取代的2-氨基吡啶,2-氨基噻唑和2-氨基苯并噻唑,以高收率提供所需的产品。
